如何显示所有结果而不以第一场比赛结束？

Question

如何显示所有结果而不以第一场比赛结束？此代码帮助我获取开始词和结束词之间的文本。但搜索在找到第一对后就结束了。您如何找到所有匹配项？const file = fs.readFileSync('./history.txt', 'utf8')const startString = '-----CompilerOutput:-stderr----------'const endString = '-----EndCompilerOutput---------------'const startIndex = file.indexOf(startString) + startString.lengthconst endIndex = file.indexOf(endString)const between = file.slice(startIndex, endIndex)console.log(between)

Answer 1

我希望我理解正确

const file = fs.readFileSync('./history.txt', 'utf8');

const startString = '-----CompilerOutput:-stderr----------';

const endString = '-----EndCompilerOutput---------------';

var startIndex = file.indexOf(startString);

while(startIndex > -1) {

    // get index after '-----CompilerOutput:-stderr----------'

    let start = startIndex + startString.length;

// -----------------------------------

// EDIT: WRONG --> let end = file.indexOf(endString);

// Need to start searching for next occurence starting at index after the start

// -----------------------------------

    // get index before '-----EndCompilerOutput---------------'

    let end = file.indexOf(endString, start);

    // get the text between

    console.log(file.slice(start, end));

    // set startIndex to next index of '-----CompilerOutput:-stderr----------'

    // if not found the startIndex value will be -1 so end of the while loop

    startIndex = file.indexOf(startString, end + endString.length);

}

示例文件：

-----CompilerOutput:-stderr----------

test1

-----EndCompilerOutput---------------

-----CompilerOutput:-stderr----------

test2

-----EndCompilerOutput---------------

输出：

test1

test2
